Attorney General Jeff Sessions said Friday the Justice Department will appeal the latest decision by a Hawaii District Court to limit the scope of President Trump’s travel ban, and blasted the court for “micromanag[ing] the decisions of the coequal executive branch.”

“[T]he district court has improperly substituted its policy preferences for the national security judgments of the executive branch in a time of grave threats, defying both the lawful prerogatives of the Executive Branch and the directive of the Supreme Court,” Sessions said.

Sessions said the court “undermined national security, delayed necessary action, created confusion, and violated a proper respect for separation of powers.”

The Justice Department will now turn again to the Supreme Court, Sessions said, calling having to do so something the Trump administration will do “reluctantly.”

The judge in Hawaii ruled Thursday night that Trump’s interpretation of the travel ban goes too far in banning family members from the United States.

Trump implemented the ban to allow people with close family ties to the U.S. enter from the six countries covered by the ban: Iran, Libya, Syria, Somalia, Sudan, and Yemen. But it said grandparents, grandchildren, brothers and sisters in law, aunts, uncles, nieces, nephews and cousins don’t qualify.
